Applied AI Engineer

Apilex is a global legaltech company building AI that transforms how legal professionals work. Powered by a proprietary database of 200M+ court decisions and legal documents, our platform delivers semantic search, contract analysis, and automated legal drafting — turning days of legal research into seconds. Since our founding, we've grown to a team of 90+ people and established ourselves as Türkiye's leading AI legal assistant. Now, we're taking it global — expanding into France, Germany, Brasil, Italy and Spain to compete in the billion-dollar legaltech market. 

What sets us apart? We don't use off-the-shelf AI. We build domain-specific, closed-circuit AI models with multi-layered verification systems that eliminate hallucinations and deliver answers backed by real citations and legal reasoning. Every feature we ship changes how lawyers work, not in theory, but in practice. 

We're looking for an Applied AI Engineer who can bridge the gap between advanced AI models and production-grade software engineering, building robust multi-agent systems and GraphRAG pipelines that scale.

What you will do?

• Take an active role in shaping the technical and architectural roadmap for the AI-powered core of the product.
• Design, develop, and optimize production-grade agent loops and cognitive architectures using LangGraph and LangChain.
• Own the orchestration, monitoring, and maintenance of complex multi-agent systems in production.
• Build, deploy, and scale high-performance GraphRAG and Agentic Retrieval pipelines.
• Develop, test, and maintain robust Python-based AI services within a distributed microservices infrastructure.
• Ensure system reliability, low latency, and cost-efficiency of AI workloads in production.
• Provide technical mentorship to the AI engineering team, setting high standards for code quality, system design, and production engineering best practices.

What are we looking for?

• Hands-on experience architecting agent loops and production-grade workflows with LangChain and LangGraph.
• Deep expertise in designing and shipping production-ready RAG, GraphRAG, and Agentic Retrieval architectures.
• Strong experience integrating and querying graph databases (e.g., Neo4j) and vector databases to build hybrid, deterministic retrieval systems.
• Solid experience with microservices architecture, REST/gRPC APIs, asynchronous programming, and containerized environments.
• Strong proficiency in Python; experience with Golang is a significant plus.
• A product-driven mindset: You care about reliability, latency, observability, and how the AI behaves for the end-user.
• Experience in technical leadership, guiding engineering teams, and driving architectural decisions.

Why join us?

We're building the AI that lawyers rely on every day, across every area of their practice — the core of how thousands of legal professionals research, draft, and reason. You'll join a team solving one of the hardest challenges in AI: making it reliable enough for high-stakes, real-world decisions. We're scaling across Europe and Latin America, shipping fast, and setting the bar for what reliable AI looks like in legal.

Whatever your role, your work here will be visible and meaningful. We're one of the fastest-growing AI companies in Türkiye, and we're looking for ambitious people who want to build the future of legal technology on a global stage.
